7 Claims.

known whereimm'etal containers were employed with suitable provision for supporting the samev after they have been moved to mixing position on. the device. It .has also been proposed to employ paper receptacles in conjunction with said mixing devices wherein a fixed stop isprovided on the mixing device standard at such levelthat after the receptacle has been raised tothe desired mixing position the fixed stop engages a fiangej on the bottom of the receptacle to support it in mixing position. I

The chief purpose of this invention is toprovide a more secure and suitable means for positioning and supporting a paper receptacle on said mixing devices and to facilitate the removal of said receptacle therefrom after the mixing operation is completed. More especially the purpose of the invention isto provide such means adapted to handle one-piece paper cups and the like receptacles which heretofore have been incapable of practical use on known devices.

The invention consists in the novel features,.

arrangements and combination of parts embodied by way of example in the apparatus hereinafter form of the invention, and the invention will be more particularly pointed out in the appended claims.

Further objects and advantages of the invention will more fully appear from the following description taken in connection with the accompanying drawings, which show by wayof example the preferred embodiment of the invention and in which: v

Fig. 1 shows a perspective view of the mixing apparatus;

Fig. 2 shows a side elevation, partly in section,

in coniunction with a one-piece paper cup and a 3 flanged extension thereof jointly providing a mixing receptacle; Y

Fig. 3 is a cross-sectional view of a segment of the device illustrating the relative position of certain of the parts and is taken substantially online HofFig.2;-

Fig. (is a front elevation, somewhatenlarged,

' and showing further details of certain features of the invention;

H8. dis a side elevation of the part shown in' Fig. 4 but with the parts in a different position; and Fig. 6 is a vertical, sectional elevation showing further details of certain features of the invention with the composite receptacle in raised position indicated by the dotted hnes shown in Fig. 2.

Referring to the drawings, and more particularly to Fig. 1; the numeral l designates a standard serving as a-supporting pedestal for the device and'carrying fixed adjacent its upper end an electrical motor 2 to the armature of which is carried a depending mixing arm or device 3 adapted -to be rotated upon actuation of the motor 2. The motor is preferabl provided with a two-speed switch l and is supplied with current by the usual plug-in cord (not shown) through which electrical current is supplied to the motor described as illustrating the present preferred under control'of a suitable electrical switch designated by reference to its movable portion 5 (Figs. '3, 4 and 6).' The standard I, motor 2, mixing'arm 3 and switches 4 and" 5 represent a general structure well known in the art and not claimed per se as my invention.

and arranged to slide vertically on said track. A

downwardly extending finger or hook 9 is secured adjacent the upper edge of the plate 8 and constructed and arranged to receive'theupper lip of a mixing receptacle (see also Fig. 6). To the rear of the plate 8 there is rigidly secured a dependent strut or longitudinal .carriage member it (see also Figs. 4 and 6) the upper end of which is provided with a rearwardly extending a u s ment portion Ii in register to engage the switch portion I which is normally resiliently held downward in oil! position and is adapted to be moved to closed position by the upward movement of the abutment II. The lower end of the strut III is provided with a forwardly extending portion I! which carries rigidly secured thereto a bottom support designated in its entirety as it and providing a substantial semi-circular seat arranged to preferably extend beyond the diameter of the mixing receptacle such as the one.

piece paper cup 18 (Figs. 6 and 2) and the arcuate '55 back portion or flange]! providing the lateral tension i I is provided, preferably made of metal,

and provided with a reduced lower portion l8 for engagemenjs within the lip of the cup l6 and with an upperlip portion IQ for engagement beneath the hook 9. It will be understood that the paper receptacle i6 and the sleeve extension l1 jointly serve as a mixing receptacle.

The lower plate 6' (Figs. 1 and 4) extends from the right outwardly beyond the track I and carries rigidly secured thereto the lower end of a spring arm 20 which extends upwardly and whose outer end is offset and constructed and arranged to provide a detent portion having an upper supporting portion 2| and a downwardly and-inclined face 22, the detent passing through a slot formed in the track member 1 and being positioned and arranged so that the portion 2| comes into'supporting engagement with a lug 23 carried on the carriage plate 8 when the carriage is in raised position (Fig. 5), to bring the receptacle into the dotted position indicated in Fig. 2; and when the detent is moved rearwardl-yto withdraw it from the lug 23 to permit the carriage to move downwardly. A bracket 24 is rigidly secured to the arm 20 and carries on its outer surface an engageable plate 25 disposed adjacent the carriage plate 8 and in such position as to be readily engageable by the hand of the operator which is used in grasping the receptacle to remove it from th mixing apparatus. To further facilitate the ready engagement of the plate 25 it is inclined outwardly and upwardly (Fig. 5). A stop 26 is provided for limiting the rearward movement of the arm'20 and detent 2|.

Operation From the foregoing, it will be readily under- .stood that when it is desired to mix a drink from ingredients placed within the paper receptacle,

l6 and with the sleeve I'l positioned as an extension to the said paper receptacle or cup, the

operator grasps the paper cup IS in one hand, inserts the lip I9 of the receptacle beneath the finger 9 (Fig. 1), slides the bottom of the cup on the seat portion 4 against the backportion I5 and still grasping the cup moves his hand upwardly; whereupon the carriage 8 with the cup positioned thereon is moved upwardly, the.

tion beneath the lug 23 to lock :the carriage in its raised position, whereupon the operator removes his hand and the mixing proceeds. After in removing the receptacle.
